3.(4 points) A student is given a 6.216 g mixture of iron filings, calcium chloride and sand. He separates the mixture and recovers 2.524 g of iron, 1.932 g of sand and 1.523 g of calcium chloride. Calculate the percentage of each component he recovered from the original mixture and the percent of material he lost during the separation process.

A mixture of sulphur and iron filings can be separated by magnetic separation. This is because iron is attracted to magnets, but sulphur being non-magnetic is not attracted. So, by bringing a magnet closer to the mixture, iron can easily separate out of it by getting attracted to the magnet and we will be left behind with the sulphur.

Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles—some of which are large enough in size to be captured with a porous material. Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring …

Likely some of the sulfur granules will get mixed up with the iron filings and trapped with them — so that this process only makes a partial separation, giving a pile of sulfur with less iron, and the second pile of iron filings with less sulfur.
